The first one was damaged in a tire blowout. I was happily able to use the same connector as the previous install. These thing are great. I Installed them because I have an injured back and bad knees. This was a very difficult chore as the location of the drain valves required me to bend and lean forward under the Travel Trailer to release them. No longer have to do this. This chore is now quick, easy and clean. However my one complaint, not product related, is the advertisement of the product. The ad and indeed the box it comes in is deceptive. It shows the product with a drain valve attached as if it comes as a complete unit. THIS IS NOT THE CASE. YOU STILL, NEED TO HAVE THE ORIGINAL VALVE OR A REPLACEMENT INSTALLED IN ORDER TO USE THESE ACTUATOR AS INTENDED. So just be aware of this requirement and ignore the pictures. Review: Works Well ! - Having a larger fifth wheel I know that there would be extra wiring required. The Valves work well once installed and no issues being 25 feet away from the switch's . I installed two and will add 3 more. ## Features - Product Type :Auto Accessory - Package Dimensions :10.27" L X5.73" W X2.88" H - Country Of Origin :United States - Package Weight :4.0Lbs ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002OW2MIK | | Brand | BARKER | | Brand Name | BARKER | | Colour | Black | | Customer Reviews | 4.2 out of 5 stars 54 Reviews | | Finish Type | Powder Coated | | Finish type | Powder Coated | | Item Dimensions W x H | 26.1W x 14.6H centimetres | | Item Weight | 907 g | | Manufacturer | Barker Manufacturing Company | | Manufacturer Part Number | 24140 | | Material | Metal | | Material Type | Metal | | Model Number | 24140 | | Number of Items | 1 | | Product Style | Modern | | Product dimensions | 26.1W x 14.6H centimetres | | Special Features | Removable | | Special feature | Removable | | UPC | 755220241404 | ## Product Details - **Brand:** BARKER - **Colour:** Black - **Finish type:** Powder Coated - **Material:** Metal - **Product dimensions:** 26.1W x 14.6H centimetres ## Images ![Barker Manufacturing Company 24140 1.5" Auto-Drain - Image 1](https://m.media-amazon.com/images/I/61-cil3FgEL.jpg) ## Questions & Answers **Q: Is the separate 12v Switch included?** A: Yes, at least it was with mine. **Q: Barkar manufacturing company 24140 1.5" auto-drain (i need full information about this part and what is this part job )** A: It is a 12v electronic waste valve for use on RV black and gray waste tank **Q: Does this valve have a prvovision to operate manually like the Valterra EZ?

The first one was damaged in a tire blowout. I was happily able to use the same connector as the previous install. These thing are great. I Installed them because I have an injured back and bad knees.

The Valves work well once installed and no issues being 25 feet away from the switch's . I installed two and will add 3 more. ### ⭐⭐⭐⭐⭐ No more need to get on your knees *by D***9 on 10 January 2026* It seems to be sturdy enough and opens and closes smoothly. Installing the valve takes less than ten minutes. The hard part is routing the wires, that took me days to complete. My water control panel is about 12' from the dump valves but finding a way to get the wires to the valves on my Motorhome was a huge challenge. I recommend installing new valves. My old valves were sticky and the light would not turn off when I closed the valve. I installed a new valve and it works perfectly now. I'm looking forward to not having to crawl on my knees to dump the tanks. ## Frequently Bought Together - BARKER Manufacturing Company 24140 1.5" Auto-Drain - Valterra T1001VPM Bladex 1-1/2" Waste Valve Body with Metal Handle , Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/636093306-barker-manufacturing-company-24140-1-5-auto-drain](https://www.desertcart.gr/products/636093306-barker-manufacturing-company-24140-1-5-auto-drain) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-12*
